Downloaded your PDF and projects - your chart project that uses seriesmapping won't compile. 
There are no detail docs on individual methods or properties.
I have been told that seriesMapping is the best way to proceed on charts.

In the code below some things work and some things don't:

    The ToolTipLegend works.
    Adding of "score" does not work.
    The chart plots 18 values along the base line where I expect the values to show the hole score...
        ChartPoints contains 18 occurances of ChartPoint
        ChartPoint MyY is a score from -1 to 4
        ChartPoint MyX is 1 through 18 (the 18 golf holes)

       private class ChartPoint
            public int MyY { get; set; }
            public int MyX { get; set; }
        private List<ChartPoint> ChartPoints = new List<ChartPoint>();

            FatigueChart.Width = chartWidth;
            FatigueChart.Height = chartHeight;
            FatigueChart.DefaultView.ChartTitle.Content = "Fatigue";
            //The legend takes up too much space. Remove it and make it appear as a tooltip...
            ChartLegend toolTipLegend = new ChartLegend()
                Background = new SolidColorBrush(Colors.Black),
                Height = 200,
                Width = 200,
            ToolTip toolTip = new ToolTip()
                Content = toolTipLegend,
                Style = this.LayoutRoot.Resources["CustomToolTipStyle"] as Style,
            ToolTipService.SetToolTip(FatigueChart, toolTip);
            FatigueChart.DefaultView.ChartLegend.Visibility = Visibility.Collapsed;
            FatigueChart.DefaultView.ChartArea.Legend = toolTipLegend;

            SeriesMapping seriesMapping = new SeriesMapping();
            seriesMapping.LegendLabel = "Fatigue Last 9 Games";
            seriesMapping.SeriesDefinition = new SplineSeriesDefinition();
            seriesMapping.ItemMappings.Add(new ItemMapping() //this didn't work
                DataPointMember = DataPointMember.YValue,
                FieldName = "Score"
            FatigueChart.ItemsSource = chartPoints;

I think I just need to get started.  What is wrong here?
